Use pulse configuration in fake Bogota, Rome, Manila and Santiago (#7688)

* Update fake_bogota.py

- refer to the defs file and turn it into a FakePulseBackend

* Update fake_manila.py

- refer to the defs file and turn it into a FakePulseBackend

* Update fake_rome.py

- refer to the defs file and turn it into a FakePulseBackend

* Update fake_santiago.py

- refer to the defs file and turn it into a FakePulseBackend

* Update fake_bogota.py

- make sure we are using FakePulseLegacyBackend where it is needed.

* Create bogota-manila-rome-santiago-as-fakepulsebackends-2907dec149997a27.yaml

- add release notes

* Update releasenotes/notes/bogota-manila-rome-santiago-as-fakepulsebackends-2907dec149997a27.yaml

no need for prelude 🎹🎵 😕

* Update releasenotes/notes/bogota-manila-rome-santiago-as-fakepulsebackends-2907dec149997a27.yaml

🧐 using proper notation.
